Abstract.We give some conditions under which minimality is equivalent to the other notions in noncommutative ergodic theory and prove that in a compact C*-dynamical system topological transitivity is invariant under exterior equivalence.
Let A be a C*-algebra and Rep(-A) the set of all nondegenerate representations of A. We define a new topology on Rep(A) and study the relations with the point weak topology of Rep(A).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citationsβcitations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
